. Speeitlcation of Letteraratent l Appiieanon ned my i4, uns. semi No. 'ze-1,620.

To all whom. it may concern Beit known thatI, SIii-:RM'OOD M.' CHASE, a citizen'of the United States, residing at (loluinbus` in the-county ofv Franklin and State of Ohio, haveinvented certain new and useful' ImprovementsA in Guards-for Bearings-,.of which the following is a speci# Y fication, reference being hadv therein tothe accompanying drawing.

. This invention `relates to dust-guards forbearings and the object of the invention is;

to provide a guard which will exclude the dust from the bearings more eiciently than the dust guards now in use.

To this end it is a further 0b]ect of the invention to provide a floating guard which will extend between ,and overlap the adjacent portions of the hub and the aring and will thus accommodate itself to the same and will effectually exclude the dust there-v from.

In the accompanying drawings, Figure 1 is a .longitudinal sectional view taken through a` hub and bearing showing my in- 'vention applied thereto; Fig. Q is a` detail perspective view of the dust guard; and Fig. 3 isan elevation, partially broken away, of the bearing to which the dust guard is fpplied. y

Inv these drawings I have illustrated one embodiment of my invention and have shown the Same as applied to a truck, indicated as a whole by the reference numeral l. and of that type .commonly employed in industrial cars. The bearing 2 is of the roller bearing type and is pivotally mounted in a bracket 3 carried by the frame of the truck. .This pivotal mounting enables the bearing to automatically aline itself with the axle 4 on which track wheels 5 are mounted. The hub 6 of each wheel is spaced a short distance from the adjacent bearing vand in order to effectually exclude the dust from the heal-in I have provided a floating dust guard or s iicld having parts overlap ping the respective ends of the bearing and hub and having another part extending between the bearing and the hub to properly position the shield with relation thereto. In the form of device here shown'this shield comprises a ring 7 of a diameter slightly to their movement.

greater than the diameter of the ends of the -bearin-g and the hub and of a width Sullicient to enable it to overla the ends of these members for a siiicient istance to prevent dust passing between the shield and said .ends This shield 'has on itsinner surface an inwardly projecting art, or parts, forming a 'stop which, in te present instance, comprises a flange 8 adapted to extend betweenthe hub and the bearing,.thereby maintaining the shield in'proper relation with the ends of these partis. In this man- -ner the shieldis free to float and may be supported 'in closev relation to and. in actual Contact with the hub and beang but owing to its floating character and its ability to move with these parts it offers no resistance Because of its relation to the hub and `bearing it' very elfectually excludesdustor dirt falling from the truck.

The term floating asl used herein. in 4connection with vtheguard ring is intended to-de'ine, that ring as having, free movement relatively to the parts with which it coperates. It is not necessarily supported out'of contactv witligtlieseparts, but the contact, when it exists, is not such as to interfere with t'he free movement of `the ring.

'hile I have shown and described one embodiment of my invention it will be understood thaty -this has been chosen for the purposes of illustration only and that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having` thus fully described my invention, what I claim as .new and desire to secure by Letters Patent, is

1. The combination, with a bearing, and a part journaled in said bearing, of a floating dust` shield com rising a flat annular body portion exten ing loosely about the end of said bearing and' having an inwardly extending radial stop. spaced awa from both edges thereof to maintain said'sliield in proper relation to said bearing, said shield bein freeto move relatively to both said bearing and the part journaled therein.

Q. The combination, with a bearing, a pai-t journaled in said bearing, and a hub Patented sept. s, 1912i.

carried by said art adJacent to said bearing,

of an annular s ield extending loosely about the part journaled in said bearing and having axially extending portions overlappin the adjacent ends of lsaid bearing and sai hub and having a portion-extending inwardly between said hub and bearing to position the shield relatively thereto, said In 'testimon whereof I aix my signature in presence o two witnesses.
